Article by Shawn McEachern created/updated November 21, 2018

Have you “Encountered invalid record index” when importing a STEP file into SOLIDWORKS?

To fix the file try the following:

  1. Deactivate “3D Interconnect” in SOLIDWORKS Options > System Options > Import
  2. Open the STEP file using text editor such as Notepad. The file will open as text.
  3. Use Search/Find, and search for: PRESENTATION_STYLE_ASSIGNMENT
    If this problematic data is found, replace it using the Search/Find & Replace command with: PRES



  4. Save the file. This parameter will now be skipped during the import’s parsing process, and thus the warning will not display and the STEP should import as expected.
  5. Retry the Import into SOLIDWORKS.
